What two numbers multiply to 221 and add up to -222?

Here we answer the question: "What two numbers multiply to 221 and add up to -222?"

The answer to your question is:

-221 and -1

Below we illustrate and prove that -221 and -1 multiply to 221 and add up to -222:

-221 × -1 = 221
-221 + -1 = -222

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x² - 222x + 221 = 0

If so, the solution to factor the quadratic equation above is:

(x - 221 ) (x - 1)

To summarize, since -221 and -1 multiply to 221 and add up -222, you know that the following is true:

x² - 222x + 221 = (x - 221 ) (x - 1)
